ABSTRACT:
FIELD OF INVENTION
The present invention relates to the field of lenticular devices for 3D viewing of images and more particularly to a device and associated method for forming the device such that a portion of the field of view of the device provides the viewer with motion images.
BACKGROUND OF THE INVENTION
Lenticular images can be used to provide the effect of motion, for example, in U.S. Pat. No. 3,268,238, entitled “Publications” by R. Finkel there is disclosed an image page formed with lenticular material that utilizes three views of a rabbit. Each view is slightly different from the other views such that rotation of the page generates a visual impression that one or more features of the rabbit move. In U.S. Pat. No. 3,538,632, entitled “Lenticular Device and Method for Providing Same”, by K. Anderson there is disclosed a lenticular display that uses images of a bucking horse and rider. An illusion of motion is imparted to the images by rotating the display. The Anderson invention is specifically directed to the painting of various portions of the images with transparent paint of different colors and shades to enhance the animation or three dimensional effect of the lenticular device.
To successfully provide a lenticular device that displays motion, it is essential that the views of each individual scene be fully extinguished so that the effect of ghosting between adjacent views is minimized as the lenticular device is rotated. It is also necessary to be able to present a sufficient number of views so that there is a sense of continuous motion or so that if the motion is to appear discontinuous there are a number of views to track the total motion to provide the viewer with the sense that the moving objects are in continuous motion, compared to jumping from one location to another.
SUMMARY OF THE INVENTION
The present invention is directed to overcoming one or more of the problems set forth above. Briefly summarized, according to one aspect of the present invention there is provided a lenticular device comprising:
a sheet of lenticular material; and
a printing on a viewing surface of the lenticular material with said printing representing a number of consecutive still images and a number of motion images.
The above and other objects of the present invention will become more apparent when taken in conjunction with the following description and drawings wherein identical reference numerals have been used, where possible, to designate identical elements that are common to the figures.
ADVANTAGEOUS EFFECT OF THE INVENTION
The present invention has the following advantages:
The present invention provides a lenticular device wherein a combination of a non-moving (still) and a motion image are viewable, within a band of viewing angles, so that a viewer may enjoy both the details of the still lenticular device's image and the motion of a motion image without having the bluriness generally associated with moving images.
In addition, compared to the prior art, this invention provides a device and a method for producing combined high-quality still and motion images that are pleasing to the viewer.
Multiple views are used to provide the viewer with a sense of continuous image motion over a substantial viewing range while additionally providing a viewing range of at least one high quality still image.
The provision for either full cycle motion, that is, at an initial viewing angle an object begins to move from a location and continues to move to return to its original location (with or without intermediate stationary images) as the viewing angle is changed or the provision for motion in the object itself (object changes shape) such that the object moves continuously in one direction through a range of motion and then jumps back to its initial shape.
The provision of a lenticular device that can change background viewing color through the range of motion while optionally changing text messages.
The ability to provide a lenticular device which viewably causes an object, through a technique called morphing, to change from one size and/or shape to another size and/or shape.
The provision of a technique for taking video images and translating them into lenticular images to provide a specific viewing sequence, or motion picture film clip.
